The effect of smartphones and playing video games on decision-making in soccer players: A crossover and randomised study

ABSTRACT

The objective of this study was to analyse the effect of the use of social networks in smartphones or playing video games on the passing decision-making performance in professional soccer athletes. Participants were 25 male professional soccer athletes (mean ± SD: age 23.4 ± 2.8 years). The participants performed three randomised conditions divided into three groups: control (CON), smartphone (SMA), and video game (VID). Before and after each experimental condition, the Stroop Task assessed the level of induced mental fatigue. Then, the athletes performed a simulated soccer match. A CANON® camera recorded the matches for further analysis on passing decision-making performance. A group effect was identified (p < .01) with impairment on passing decision-making performance for the SMA (p = .01, ES = 0.5) and VID (p = .01, ES = 0.5) conditions. We concluded that the use of social networks on smartphones and/or playing video games right before official soccer matches might impair the passing decision-making performance in professional soccer athletes.     

Assessing Determinants of Perceived Ease of Use of Institutional Repositories by Lecturers in Nigerian Universities

Abstract

Institutional repositories (IRs) present platform to disseminate research findings to complement the traditional scholarly communication model. The use of IRs is beneficial to authors, host institutions, libraries and society at large. Despite the numerous benefits of IRs, there is low deposit of scholarly works by lecturers and the investment on IRs seems to be a waste. This study examined determinants of perceived ease of use (PEOU) of IRs by lecturers in Nigerian universities. A survey of lecturers received 857 respondents. Awareness, anchor and adjustment factors were found to be determinants of PEOU of Institutional repositories by lecturers in Nigerian Universities.     

Factors that influence behavioral intention to use mobile-based assessment: A STEM teachers’ perspective

Teachers' role can be catalytic in the introduction of innovative digital tools in order to create new learning and assessment opportunities. This study explores science technology engineering and mathematics (STEM) teachers' intention to use mobile-based assessments in the teaching practice. The study proposes the teachers' acceptance mobile-based assessment (TAMBA) model which extends the technology acceptance model by introducing individual, social, institutional and instructional design factors. An appropriate questionnaire was developed and answered by 161 STEM teachers from 32 European countries. Their responses were analyzed using structural equation modeling. The proposed TAMBA model explains about 50% of the variance in teachers' intention to adopt mobile-based assessment. Perceived Ease of Use was found to be the most important determinant in teachers' intention to use mobile-based assessment. Facilitating Conditions and Output Quality were the most influential external variables in the model. The study findings revealed that focusing on mobile assessment quality design as well as on institutional support are important factors for STEM teachers in order to accept mobile-based assessments in schools.     

“There is a fine line between one’s personal life and professional one”: handling employee sexual harassment on facebook from the victim’s perspective

Sexual harassment is an interdisciplinary topic in organizational research that has received increased attention with the rise of the #MeToo movement. The online environment has complicated the experiences of employees who are sexually harassed by a coworker. One particular medium where online sexual harassment occurs is on social networking sites (SNS), such as Facebook. This research report examined how victims of sexual harassment believe organizations should handle online sexual harassment. We qualitatively coded 153 responses to the question, “What else do you think employers could do to handle sexual harassment on Facebook?” Our findings demonstrated a clear tension between whether harassment on Facebook is a private concern of the employee or a public concern of the employer/organization. Some victims advocating keeping work friends off of Facebook, while others suggesting having open door policies, conversations, and/or trainings. The difference in these approaches illuminates how the victims grappled with the public/private tension, and whether the organization should be made aware of their situations or if victims should handle it themselves. Implications of this research suggest that the blurred boundaries between employee face-to-face and online sexual harassment should continue to be explored, including why victims report harassment and to whom they report it.
